perl v5.34.0                                       2022-06-15                   MARC::Crosswalk::DublinCore(3pm)

       This module provides an implentation of the LOC's spec on how to convert metadata between MARC and Dublin
       Core format. The spec for converting MARC to Dublin Core is available at:
       http://www.loc.gov/marc/marc2dc.html, and from DC to MARC: http://www.loc.gov/marc/dccross.html.

       NB: The conversion cannot be done in a round-trip manner. i.e. Doing a conversion from MARC to DC, then
       trying to go back to MARC will not yield the original record.

       To install this module via Module::Build:

               perl Build.PL
               ./Build         # or `perl Build`
               ./Build test    # or `perl Build test`
               ./Build install # or `perl Build install`

       To install this module via ExtUtils::MakeMaker:

               perl Makefile.PL
               make
               make test
               make install

new(%options)
       Creates a new crosswalk object. You can pass the "qualified" option (true/false) as well.

               # DC Simple
               $crosswalk = MARC::Crosswalk::DublinCore->new;

               # DC Qualified
               $crosswalk = MARC::Crosswalk::DublinCore->new( qualified => 1 );

   qualified($qualified)
       Allows you to specify if qualified Dublin Core should be used in the input or output. Defaults to false
       (DC simple).

               # DC Simple
               $crosswalk->qualified( 0 );

               # DC Qualified
               $crosswalk->qualified( 1 );

   as_dublincore($marc)
       convert a MARC::Record to a DublinCore::Record.

   as_marc($dublincore)
       convert a DublinCore::Record to a MARC::Record. NB: Not yet implemented.
